Welcome home Kid.
Well of course he didn't tell you. Your brother likes his secrets.
You can kill me or not. Either way, I win.
The Mirakuru isn't what made me hate you! The end is near, but maybe I'll be merciful enough to let you live and see your city burn!
Lance: You've killed before. Tonight I suggest you get back in the habit.
Felicity: He's wrong.
Oliver: He's right.
Slade: Goodbye Mr. Blood.
Sebastian: I loved this city!
Moira: There's only one way this night can end and we both know that, don't we, Mr. Wilson?
Moira: Please tell me both my children will live.
Thea: Mom! What are you doing?! Mom!
Moira: Thea, I love you. Close your eyes baby!
Slade: You possess true courage. I am truly sorry you did not pass that on to your son.
Oliver: Oh you psychopath! Shado...Shado wasn't yours!
Slade: No. She was yours. Until you chose another woman over her!
Slade: Don't worry. I am not here to harm you.
Laurel: Go to hell.
Slade: All in good time, I'm sure. But before then, I've come to Starling City to see Oliver Queen suffer.
Laurel: Oliver? What?Why?
Slade: Because he's not the man you think he is.
Laurel: How would you know that?
Slade: Because I know Oliver Queen is The Arrow.
Your brother has a secret, Thea. Would you like to know what it is?
Oliver: How'd you get off the island?
Slade: That is your first question/
Oliver: Well, you've made it pretty clear that you're not going to tell me where my sister is so, yeah, that is my first question.
Oliver: They're calling you Deathstroke.
Slade: That's a bit flamboyant. I like it.
